In doped ZnS Thin FilmsFrom 2014 to 2018 the number of “thin films” scientific publications have raised by almost 75%. More than 140.200 publications related to thin films from the main scientific journals (Nature, Elsevier, Springer, Taylor & Francis, and Wiley) have been examined to deem its main study topics. *

New material characterization and manufacturing” is the principal research topic representing 44% of the scientific literature analyzed related to thin films. This topic includes changes in thin film properties relative to electronics, optics, magnetism, and mechanics.

The next research topic with high presence is “solar cells characterization“, representing 17% of all literature analyzed. For those characterizations, they analyse layers or multilayers of different films deposited by PVD sputtering techniques, like perovskite/CIGS (multilayer film made of copper, indium, gallium, and selenide), layers doped with plasmons or kesterite/CZTSSe (multilayer film made of copper, zinc, tin and selenide/sulfur-selenium,).

The third research topic is the use of “electronic and conductivity properties” to achieve faster and reliable electric devices, with the 16% of the articles. It’s important to remark the fact that almost 20% of those studies are about superconductive layers.
 
Using the same methodology with Spanish and Portuguese publications, 600 thin film articles have been counted and analyzed from the same journals and CSIC publications to compare the principal topics and research lines with the global average, within the same period. The principal ranking topics remain the same, but there are some differences in the subtopic of “solar cell characterization“.

The main differences appear in solar cells characterization. The principal layers used in this case are kesterite layers and in a smaller proportion, perovskite layers. Those layers are in primary research phases but, it seems that in Spain and Portugal it’s taking more and more strength.

A refurnished geophysical science laboratory in a wide Midwetern Research University is now equipped with a new FIB/FESM, and searches to maximize the use and results from their new machine.

As most of their applications are related to earth science study, they regularly coat and polished sections of rocks and meteorites who generally have tiny, sometimes submicron grains.

Geologists generally prepare samples for microanalysis, by coating them with gold or carbon (Gold, for secondary ion mass spectrometry as it is mono-isotopic with a low ionization yield; carbon minimizes overlap in x-ray microanalysis), also other sample metals are prepared. Nevertheless, it remains of critical and particular importance for the geologist’s ´ laboratory to reduce hydrocarbon background during coating, as hydrocarbon background can cause overlaps when coated specimens are analyzed with secondary ion mass spectrometry.

The geology Laboratory had made a long-standing use of a 30-year-old diffusion-pump bell-jar type carbon coater and regularly numerous instances of hydrocarbon background-induced overlaps are encountered.

To reduce this hydrocarbon background in spectroscopy, sample preparation with Denton Vacuum Desk V TSC, recommended by, with its turbo molecular pumping package will have a crucial role.

Due to hydrocarbons backstreaming from the oil present both in any diffusion pump and also in rock sample, significant hydrocarbon background peaks are often occurred observed in spectroscopy..

A large variety of high vacuum applications uses turbomolecular pumps specially the ones demanding clean and truly oil-free vacuum.

The single-ended, turbomolecular pump is often used to replace a same size diffusion pump in existing systems.

Besides the absence of oil on the backing-vacuum side, which will contribute to significant hydrocarbon background reduction when performing the SEM sample preparation, a turbomolecular pump provides more facility for maintenance and wear.

The following points are Desk V TSC characteristics:

  • Hydrocarbon-free sample preparation
  • 70 l/s turbo molecular pump
  • Full range high vacuum gauge
  • Capable of sputtering all metals
  • Provides finer grained films
  • Enhanced touchpad with graphics capability
  • Manual or automatic timed sputtering or etching
  • Choice of adjustable current control to permit either high or low rate sputtering to achieve finer grain structure
  • Sample specimen protection from damage via Denton’s patented anode grid which, in conjunction with the magnetron sputter head to collect stray electrons, prevents them from bombarding/heating the simple

Graphene at the MWC 2017

The Mobile World Congress (MWC) is an annual event held in Barcelona, which brings together

thousands of device manufacturers, vendors, mobile operators, technology providers and tech

enthusiasts from all over the world. It is world’s largest gathering for the mobile industry, this year

event took place from 27 th February to 2 nd February in Fira Gran Via and we could not miss it.

This year main theme was “THE NEXT ELEMENT”. As always, there were new phones announced,

we could also see a flood of Virtual Reality (VR) and Augmented Reality (AR) devices,

announcement and presentation of revolutionary 5G technology, new Nokia 3310 and even

smarter cars. But we find the “NEXT ELEMENT” to be carbon, in particular – graphene.

During last day of the conference there was an all-day- long workshop dedicated to the material re-

invented in 2004 by two professors of University of Manchester (2010 Nobel Prize winners in

Physics). And what’s interesting, one of the speakers was a member of the winning duet,

Konstantin Novoselov.

Mr. Novoselov presented history of the discovery, unique properties of the material together with

other mono-layer materials and its applications. He has also introduced graphene mass production

methods:

– chemical vapor deposition (CVD) applicable for photonics, electronics and coatings,

– growth on silicon carbide(SiC) for electronics and RF transistors,

– liquid phase exfoliation for coatings, composited, energy and biological applications,

– molecular assembly for nano-electronics,

– mechanical exfoliation for research and prototyping (interestingly, might be done with

scotch tape).

Other speakers gave insights on successful implementations of graphene and its future

applications in photonic devices for telecom and datacom, high-speed data link, wearables,

flexible printed electronics, various sensors and many others. The workshop session ended with

discussion panel and group discussion.
